Hmm, can you elaborate on this point a little more?
In what cases will route still hang? I guess in the
cases where the needed information is not found in the
neccessary file (/etc/hosts?). IMHO, this is a perfectly
valid behaviour. Same things happens if you invoke 
nslookup and you dns-server is not answering.

Either you have a working dns, then you should use dns,
or you don't, in which case you'll have to use the files
for lookup. Or you don't do any lookup at all.

Well, this might be annoying, but I don't see a general fix for
the missing dns-server problem, besides shortening the timeout
period, in which case you'll have unneeded failures.

Or do you think that the name-server problem is special in
conjuntion with the route command? Maybe we can have a -n switch
for route like we have it for netstat (that is, if we don't
have this already, I can't check right now)?
